Old Stream Map V 1.2 Page

: Uses LiDAR (Light Detection and Ranging) data to highlight depressions in the earth where streams once existed, even if they are now paved over or dry.

: A granular slider that transitions the map view from current satellite imagery to 19th-century hydrographic surveys and geological "best-guess" paleo-channels.

: Identifies "lost" streams that have been diverted into underground culverts or sewer systems, marked with a distinct dashed neon-blue line. New in Version 1.2

: A mobile-integrated view that allows users to point their phone at a dry valley or street corner to see a 3D simulation of the original water flow.
